Title: Private-power-generation-type floating body structure
Inventor: YAMADA YASUO
IPC: B63B21/02
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a stable emplaced/fixed state and to facilitate evacuation movement by installing a private power generating device in a floating structure and operating an electromagnet with the power. SOLUTION: When electromagnets as an electromagnet 3 and a polarizing body 2 are used, the electromagnets are operated by power generated by a solar power generating device 4. Since the facing electromagnet 3 is operated with power from the solar power generating device 4, the polarizing body 2 and the electromagnet 3 are adsorbed to each other or are attracted with each other in a separation state, and therefore, a floating structure 1 can be fixed on a sea surface over the polarizing body 2 installed at a position for emplacing/ fixing it. When the sea surface is expected to be rough due to approach of a storm, power supply to the electromagnets are cut when the electromagnets are used as the electromagnet 3 and the polarizing body 2, and the floating structure 1 can be evacuated and moved to a safety place with a self-propulsion device 5.

Title: Shell of intake air controlling device of internal combustion engine
Inventor: ITO TAKAYUKI
IPC: F02M35/10
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To reduce warp of a flange part for mounting, reduce deformation of a cylindrical bore part and improve roundness by making a shell of an intake air controlling device from a resin material and forming the outer peripheral shape of the mounting flange part into a round shape or a shape close to the round shape. SOLUTION: This shell is constituted of a cylindrical bore part 11, a flange part 12 for mounting, a butterfly valve shaft receiving boss part 13, a hole 14 for inserting mounting bolt, a stopper (closed) 15, a stopper (opened) 16 and a spring mounting seat 17. When stress deforming the cylindrical bore part to the inside by contraction, warp and deformation are generated because supporting force for overcoming stress is insufficient in the flange part 12 for mounting because the outer peripheral shape of the flange part 12 is formed into plane and linear shapes when the outer peripheral shape is formed into a square shape.  On the contrary, when the outer peripheral shape of the flange part 12 for mounting is formed into a round shape or a shape close to the round shape, the flange part 12 is capable of standing stress because supporting force is large even if stress is acted due to contraction of the cylindrical bore part, and warp and deformation can be remarkably improved as compared with the case where the outer peripheral shape is the square shape.
